Thoroughly satisfied!
I am thoroughly satisfied with my recent purchase from 1A auto. This is my third order with them and consider them to be my "Go To" online auto parts company. With each order I received professional service, good quality, orders arrived on time as promised and the pricing was well below dealers and usually other online auto sites.
I am well please with 1A auto and have no reason to shop with any other company.
Thank you 1A....

Working fine
Easy to order, speedy delivery. As for the product, I haven't had any leaks or other issues for the first week. Time will tell how durable they are. It is also worth mentioning that the covers come with the gaskets that fit right in to the matching cover.

Very good fit. Highly recommend since they are priced well below OEM. They are worth the money spent.

Does it comes with gasket and spark plug seals ?
Roman V on Nov 11, 2015
BEST ANSWER: Yes, mine did come with both. The spark plug seals are molded in so you can't really replace just those.
Where are these valve covers manufactured and are they OEM quality.?
Ed D on Apr 16, 2018
BEST ANSWER: Not sure where they are manufactured but the quality was excellent and I have had no problems since installation
